This entry was published at least two years ago (originally posted on November 29, 2021). Since that time the information may have become outdated or my beliefs may have changed (in general, assume a more open and liberal current viewpoint). A fuller disclaimer is available.
Updated my iOS “Blog This” shortcut (for sending selected text from Safari to Ulysses in Markdown format) to add two fixes: slightly adjusting the output if no text is selected, and expanding relative URLs (my thanks to Memory Alpha for inspiring this fix).
